Check of serviceability and replacement of the fan of system of cooling and муфты its couplings

In order to avoid possible damages or reception of traumas AT ALL do not start the engine with the damaged fan. Do not try to make repair of blades of the fan - in case of damage крыльчатки replace the fan new.

Check

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery and shake the fan forward-back a hand, checking it муфту on presence of signs excessive люфта.
  2. At cold (and not started) the engine повращайте крыльчатку the fan manually. The fan should rotate freely.
  3. Examine the fan outside, trying вывить traces of leaks of a liquid from assemblage вязкостной муфты. In case of revealing of signs of malfunction replace муфту.
  4. At completely heated-up engine switch off ignition and disconnect a negative wire from the battery. Turn the fan manually. Appreciable resistance Should be felt small, but. If the fan rotates freely, replace муфту.

Replacement

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery. Give fixing bolts and lift a fan casing, having bared cuts in the bottom arm of a radiator, then transfer a casing through the fan.
  1. Give bolts of fastening of a casing of the fan.
Details of assemblage of the fan of cooling of engine V8
  1. For fan removal on engines V8 the special tool is required, to get which it is possible almost in any of shops of automobile accessories. The fan fastens to the water pump by means of the big central nut which are a part of a drive of the fan. The tool grasps four bolts of a pulley of the pump whereas the central nut is given by the big key (a carving right and to give a nut follows counter-clockwise). Sometimes the pump pulley can be fixed, strongly enough having pressed tape type приводной a belt, however in a case if the fan has staid on the car already long enough, tool application appears inevitable. The fan of the 6-cylinder engine fastens to the water pump by means of four hairpins with nuts; give nuts and remove the fan in gathering with муфтой couplings from hairpins.
  2. Take assemblage of the fan with муфтой and its casing from an impellent compartment.
  1. Take assemblage of the fan with муфтой and a casing.
  1. Carefully survey a condition of blades крыльчатки. In case of detection of defects make fan replacement.
  2. At the given stage крыльчатка can be отболчена from муфты couplings (if in it there is a necessity). To store the fan follows, having laid downwards the party turned to a radiator.
  1. Give four bolts and separate крыльчатку from муфты couplings - to store муфту follows stacking necessarily DOWNWARDS the party turned to a radiator.
  1. Installation make upside-down. Track reliability and uniformity of a tightening of nuts of fastening крыльчатки and муфты.
